Introduction to Right Angles
We’ve launched into our new unit…2D Geometry! Today we explored angles. We focused mostly on right angles which are 90 degree angles that make an L shape. Students went on a scavenger hunt looking for at least 3 things in our classroom that had angles less than 90 degrees, 3 things that were exactly 90 degrees, and 3 things that were greater than 90 degrees.
There were some amazing searching skills as students mentioned certain letters of the alphabet such as “V” had angles less than 90 degrees. Other students looked at scissors and noticed that when you opened them, they made an angle less than 90 degrees.
We learned that we could use our notebook corner to help us measure and compare.
What are some objects around your house that you could add to your chart?
